Wear-resistant steel ball technology upgrade to promote industrial grinding innovation ** A mining machinery factory has significantly improved the production efficiency and quality of wear-resistant steel balls through automatic production line transformation (semi-automatic forging, double-ended rolls, etc.) and product innovation, and successfully expanded overseas markets. These breakthroughs solve the pain points such as single industry specifications and low efficiency, and promote the overall development of the industrial grinding field. In the future, technological progress will continue to enhance the application value of wear-resistant steel balls in mining, cement and other fields.
